The purpose of blind source separation is to separate the original sources from the sensor array, without knowing the transmission channel characteristics. Besides methods based on independent component analysis, several methods based on time-frequency analysis have been proposed. In this paper, a new method of multistage separation is proposed, which improves our formerly proposed methods using the time-scale information matrix based on the continuous multiwavelet transform.

Vector based forwarding (VBF) directing protocol is an area based vitality effective steering convention intended for submerged acoustic sensor systems (UASNs). In this paper a VBF-enhanced directing convention is proposed, which utilizes the data of area as well as the remaining vitality and the quantity of retransmission in last cycle to settle on choice whether to make information sending. The channel attributes for various channel models are examined and a superior parcel conveyance proportion is gotten. As per the reproduction results, all the more equitably vitality utilization and solid information transmission are accomplished in our proposed convention.
